Description

Dishwashing Liquid Detergent Composition {COMPOSITION OF DISHWASHING DETERGENT}

The present invention relates to an opaque dishwashing liquid detergent composition excellent in biodegradability, low irritation to the skin and excellent in decontamination ability.

In general, household liquid products containing a large number of surfactants, such as kitchen detergents or shampoos, can be divided into a transparent storage, a product with a pearlescent effect, and an opaque product without a pearlescent effect.

Non-transparent products generally include, for example, behebic acid, or pearlescent or pearlescent agents, higher fatty acid esters of polyethoxyethanol, palm oil fatty acid alkanol amides, and lauryl ether sodium lactate. Various opacity agents are used.

However, when producing an opaque product having no pearlescent effect, the opaque agent must also satisfy various requirements. For example, the content of solids should be lowered to reduce possible storage costs and to be rheologically satisfied. In addition, it is particularly important that the dispersed particles be made very small to prevent gradual sedimentation. In addition, opacity should be formed while the effect of pearlescent is small.

Generally, pearlescent opacifiers include ethylene oxide added to alkyl glycol fatty acid esters of 16 to 18 carbon atoms, wax esters, hydroxy triglycerides, saturated fatty alcohols, fatty acid compounds of 16 to 18 carbon atoms, and paraffin wax. Things. Among them, the most commonly used are opaque agents in the form of alkyl glycol fatty acid esters represented by the following formula (4),

[Formula 4]

R ⁷ CO-O- (A ₂ ) -OR ⁸
